Issue Description

Every rich-text field in the admin panel costs one query per attribute in the installation,
because <x-admin::tinymce> rebuilds the workflow placeholder list on each render.

Where the queries come from.
packages/Webkul/Automation/src/Helpers/Entity/AbstractEntity.php:63 — getAttributes()
walks every attribute of an entity type and reads $attribute->options, a lazy hasMany on
attribute_options, so one SELECT per attribute:

foreach ($this->attributeRepository->findByField('entity_type', $entityType) as $attribute) {
    ...
    $options = $attribute->options;      // one query, per attribute

Entity::getEmailTemplatePlaceholders() (Entity.php:89-101) runs that for all eight
entities in config('workflows.trigger_entities'), and the TinyMCE component calls it on the
first line of its template
(packages/Webkul/Admin/src/Resources/views/components/tinymce/index.blade.php:1):

@php($placeholders = app('\Webkul\Automation\Helpers\Entity')->getEmailTemplatePlaceholders())

so the whole walk repeats for every rich-text field rendered on the page — lead views,
person views, the mail composer, email templates, webhooks and workflows.

Measured (MySQL 8.0, queries per getEmailTemplatePlaceholders() call):

One extra query per attribute — and adding attributes is what the attribute system is for,
so the cost is lowest on a fresh install and grows with real use.

Preconditions

1. Krayin master @ 2c12091 (Core::KRAYIN_VERSION 2.2.6), also present in v2.2.5.
2. PHP 8.3.33, Laravel 12, MySQL 8.0.

Steps to reproduce

1. In php artisan tinker:

DB::enableQueryLog();
app(\Webkul\Automation\Helpers\Entity::class)->getEmailTemplatePlaceholders();
count(DB::getQueryLog());     // 19 on a fresh install

2. Add ten custom attributes under Settings → Attributes (any entity type, type select).
3. Repeat step 1: the count is now 29 — one more query per attribute added.
4. Open any admin screen with a rich-text field and read Laravel Debugbar's Queries tab:
   the same select * from attribute_options where attribute_id = ? series appears once per
   editor on the page.

Expected result

• Building the placeholder list costs a constant, small number of queries, and does not
  repeat for each editor on a page.

Eager-loading the options in the one place that reads them is enough — measured 10 → 2 on
the leads entity type alone:

foreach ($this->attributeRepository->with('options')->findByField('entity_type', $entityType) as $attribute) {

Since the placeholder list is identical for every editor on a page, memoising
getEmailTemplatePlaceholders() per request would remove the repetition as well.

Actual result

Each rendered rich-text field issues one query per attribute across all eight trigger
entities, and the total rises by one for every attribute an admin configures.

This may be the mechanism behind #980 ("Create WorkFlow Query Way Too Much!"), which was
closed as not reproducible on an empty dataset — the cost scales with configured
attributes, and a fresh install has almost none.
